Facebook - big brother?

Facebook has changed its layout again and added a "mini-feed" listing all actions a user did during the day/week/year. I was also wondering why they didn't add a blog function earlier. The whole portal is morphing into the biggest data accumulation plattform I've ever seen.

It's only a matter of time until the facebook engine starts speculating about its users: "Mike was 5 minutes logged off. Maybe he had to rush for the loo?", "Nick is already 10 minutes away - he must be wanking!" ... Soon, we'll have custom-made advertisments, fitting all the student's preferences and properties.

Sheesh, I start to sound like Thomas - he's the conspiracy theorist.
